Abstract

The tissue copper and metallothionein-Cu (MT-Cu) content of kidney and liver were measured in mutant (hemizygous macular male and homozygous macular female), heterozygous macular female and normal mouse. The tissue copper and MT-Cu contents in kidneys from 7-8 day mutants and heterozygotes were significantly greater than those of the normal kidney. Marked elevations in kidney copper and MT-Cu contents were also observed in the 8-9 week mutant (which achieved long-term survival with a single dose of subcutaneous copper administered at day 7) and in the heterozygote. The L-[35S]cystine incorporation experiments also revealed an abnormal synthesis of renal MT in the 8-9 week mutant and in the heterozygote. In contrast to kidney Cu levels, the tissue copper and MT-Cu contents of 7-8 day normal livers were extremely high, whereas the tissue copper and MT-Cu contents of mutant and heterozygote livers were extremely low. The tissue copper contents of livers of 8-9 week mutants and heterozygotes were slightly low compared to normal, and the MT-Cu contents of livers of the 8-9 week mouse were extremely low in all groups. In contrast to the changes in copper content, the changes in tissue zinc and MT-Zn contents in kidney and liver were slight in the 7-8 day and 8-9 week mouse.
